[QUOTE="SPark_South_Oz, post: 87917, member: 17032"] Not sure if this is the reason yours happened . . . but there have been a lot of flyaways reported over on the Mavicpilots forum of late. In a lot of the analysis done, there are numerous instances of compass error and correction. Interesting to note, this is not the sometimes magnetic interference warning you can get if taking off around metal etc, it happens not long after take off. Where when readying for take off, the compass is registering 180 degrees to what it should be . . . the little red arrow vs the direction it's placed on the ground. After take off, there is a recognition of this from the positioning, the bird tries to correct itself and usually goes off sideways at a rate of knots. If there is time before wind catches it, or it crashes etc, it MAY correct on its own, but very often it's not seen again. There is NOTHING you can do about this apparently, putting into sports mode or hitting pause does nothing to stop this happening. Quite a dilemma for many of the Mavic variants. Before flight when the little lady says home point recorded, please check it on the map, I do look and make sure the red arrow is pointed roughly the same direction as the drone is facing. Good habit to get into. Hope you have no further problems. [/QUOTE]
